Almost every household has furniture made of boards or panels, but have you ever wondered how these boards are produced? A small piece of board actually goes through many processes and passes through layers of inspection before finally reaching our homes. Let's take eco-friendly boards as an example and see how ordinary core boards are transformed into high-quality boards in Moganshan.
1. Core board selection
The core board of the eco-friendly board is made of high-quality fir core strips. The selected core strips are not allowed to have decay, holes, missing edges, or cracks. The middle board and poplar bark are selected to be free of decay and cracks. Light-colored poplar bark is strictly prohibited from having obvious black dead knots.
2. Production Process
Raw material sorting → 1st gluing → 1st cold pressing → 1st hot pressing → 1st scraping → substrate curing → 1st sanding → 1st semi-inspection → 2nd sanding → 2nd gluing → 2nd cold pressing → 2nd hot pressing → 2nd semi-inspection → light sanding and trimming → substrate inspection → finished product lamination → finished product inspection → packaging and storage
Explanation of key production processes
Raw material sorting
Remove garbage from the board surface (sawdust, glue solidification, etc.);
Improve the flatness of the board surface.
One-time glue
Glue the core board and assemble it with the middle board.
One-time hot pressing
The glue is cured by the instrument.
One scrape
Use putty to repair core board defects.

3. Testing Items
1. Surface wear resistance: wear value ≤80mg/100r;
2. Surface crack resistance: above level 5;
3. Surface resistance to water vapor: no protrusions, discoloration or cracking;
4. Dip stripping: The stripping length of each adhesive layer on the specimen shall not exceed 25mm;
5. Formaldehyde emission: in line with national environmental protection level standards.
Look, after many processes and careful inspection, we have the high-quality boards that we often see.
